  4. EarwigBot's Core
  5. This (should) not be run directly; the wrapper in "earwigbot.py" is preferred,
  6. but it should work fine alone, as long as you enter the password-unlock key at
  7. the initial hidden prompt.
  8. The core is essentially responsible for starting the various bot components
  9. (irc, scheduler, etc) and making sure they are all happy. An explanation of the
  10. different components follows:
  11. EarwigBot has three components that can run independently of each other: an IRC
  12. front-end, an IRC watcher, and a wiki scheduler.
  13. * The IRC front-end runs on a normal IRC server and expects users to interact
  14. with it/give it commands.
  15. * The IRC watcher runs on a wiki recent-changes server and listens for edits.
  16. Users cannot interact with this part of the bot.
  17. * The wiki scheduler runs wiki-editing bot tasks in separate threads at
  18. user-defined times through a cron-like interface.
  19. There is a "priority" system here:
  20. 1. If the IRC frontend is enabled, it will run on the main thread, and the IRC
  21. watcher and wiki scheduler (if enabled) will run on separate threads.
  22. 2. If the wiki scheduler is enabled, it will run on the main thread, and the
  23. IRC watcher (if enabled) will run on a separate thread.
  24. 3. If the IRC watcher is enabled, it will run on the main (and only) thread.
  25. Else, the bot will stop, as no components are enabled.
